BOTTOM STRUCTURE FOR METALLIC RECEPTACLES.

Specification of Letters Patent. Patented; Dec, 26, 1916.

Application filed June 9, 1913. Serial N 0. 772,653.

To all whom it may concern:

Be it known that I, ALBERT L. ADAMS, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Bottom Structure for Metallic Receptacles, of which the following is a specification.

The present invention relates to improvements in bottom structures for metallic receptacles, one object of the present invention being the provision of a structure of this character, by means of which the bottom is securely positioned and held in place without the employment of solder and the subsequent expense of heating and the acid in consequence thereof, the present invention contemplating a means whereby the adjoining edges of the receptacle and bottom are properly interlocked and are sealed with a heat and weather resisting cement so as to practically make the receptacle water tight, thus cheapening the cost of manufacture without in any way impairing the durability or usefulness of the article.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a vertical sectional view through a metal basket constructed according to and embodying the present invention. Fig. 2 is a top plan view of a portion of the bottom blank thereof. Fig. 3 is an enlarged detail sectional View through the joint between the bottom and lower edge of the receptacle, the cementitious part thereof being exaggerated to clearly show the position thereof relatively to the conjoining parts. Fig. 4 is a view illustrating the initial step in interlocking the flanges of the wall and bottom of the receptacle.

Referring to the drawings, the numeral 1 designates a metal receptacle, which in the present case is made in the form of a basket or open ended bucket, the walls of which are made of a single blank and are corrugated as at 2, so that their lower edge 3 may be to all practical purposes formed into a single edge and bent, as clearly illustrated in Fig. l, to form with the bottom as will presently appear, an overlapping and interlocking joint.

The bottom t is preferably cut in the form of a disk and at the peripheral edge has formed therein, the narrow V-shaped incisions or slots 5 which provide the respective tangs 6. In producing the turn over edge of the bottom to interlock with the edge 3 of the wall of the receptacle, the periphery of the bottom is bent upon the dash line 7, as shown in Fig. 2, the length of the incisions 5 being preferably and approximately two-thirds the length of the full turn over, so that when the respective edges 3 and the turned portion of the bottom 4 are in interlocking position, the same will assume the position, as shown in Figs. 1 and 3, producing an exceedingly close joint and one which will prevent the tendency of the bottom 4 when receiving weight thereupon, to pull away from the turned-in edge 3 of the body 1.

In order to make the joint water-proof, and at the same time dispense with employing a metal solder, and the consequent use of heat and acid necessary therewith, the cement 8 is placed so as to seal the spaces between the adjoining portions of the bottom and body of the receptacle, as clearly shown in detail in Fig. 3, said cement being applied with a brush or rag as may be desired, and at a temperature slightly above atmospheric temperature. Said cement is preferably composed of a water resisting material such as Eureka steam joint cement or its equivalent, and contains an evaporating or siccative vehicle, which will permit the cement to properly dry when exposed to the air and thus seal the joints to prevent leakage of the receptacle through the bottom.

In initially setting the bottom upon the turned edge 3 of the receptacle, said turned edge 3 is first bent-up, as clearly shown in Fig. 4, while the peripheral edge of the bottom 4 is bent downwardly, as shown in Fig. 4, so that the respective edges of the receptacle 1 and bottom 4: will slightly overlap, so that when pressure is exerted'upon opposite sides of the overlap or joint, the adjacent portions having applied thereto, the cement to form the water tight joint, the flanges will fold or bend, as clearly shown in Figs. 1 and 3, and thus produce a neat and tight joint at such points without the employment of heat or metal solder.

What is claimed is Areceptacle having asheet metal body and a sheet metal bottom the adjacent portions of which'lie in parallel planes, the lower edge of the body being inturned and provided with an upper outwardly bent portion, and the bottom having its marginal edge bent downwardly and inwardly and interlocking with said edge of the body, the inwardly bent margin of the bottom being provided with a series of incisions extending inwardly from the periphery and terminating short of the bend to provide a continuous or unbroken portion of the metal at the bend and adjacent to the continuous margin of the lower edge of the body, and cement interposed between the adjacent portions of the body and bottom, and covering that portion of the bottom provided with.
